Reflecting on my overly grumpy last post, also every bit many recent Krugman columns, I intend at that spot is actually a commutation consensus here.
There is, inward fact, a abrupt separate betwixt macroeconomics used inward the pinnacle levels of policy circles, too that used inward academia.
Static ISLM / ASAD modeling too thinking actually did pretty much disappear from academic query economic science or too thus 1980. You won't detect it taught inward whatever PhD programs, y'all won't detect it at whatever conferences (except the occasional lunchtime "keynote speech" where an Important Person from the policy basis comes inward to enlighten us), y'all won't detect it inward whatever academic journals (AER, JPE, QJE, Econometrica, etc. etc.). "New-Keynesian" DSGE (Dynamic Stochastic General Equilibrium) models are much inward vogue, but bring actually cipher to practise alongside static Keynesian ISLM modeling. Many authors would similar it to live so, but when y'all read the equations y'all volition detect these are only utterly dissimilar models.
Static ISLM thinking pervades the upper reaches of the policy world. "Thinking" as, sadly, quantitative modeling of that see disappeared inward the mid-1970s. But if y'all read the analysis guiding policy at the IMF, the Fed, the OECD, the CBO; too the larger policy fighting inward the pages of the Economist, New York Times, too quite oft fifty-fifty the Wall Street Journal, policy analysis is pretty much unchanged from the Keynesian ISLM, ASAD, analysis I learned from Dornbush too Fisher's textbook, taught inward Bob Solow's undergraduate Macro course of didactics at MIT virtually 1978. The staffs at these agencies write prissy academic full general equilibrium papers, but entirely inward their "research" activities.
Thus, if y'all read Krugman's columns, y'all volition come across him occasionally crowing virtually how Keynesian economic science won, too how the disciples of Stan Fisher at MIT bring spread out to piece of job the world. He's right. Then y'all come across him complaining virtually how nobody inward academia understands Keynesian economics. He's correct again.
Perhaps academic query ran off the rails for xl years producing cipher of value. Social sciences tin practise that. Perhaps our policy makers are stuck alongside elementary stories they learned every bit undergraduates; and, every bit has happened countless times before, novel ideas volition percolate upwards when the generation trained inward the 1980s makes their agency to to pinnacle of policy circles.
I intend nosotros tin grip on something. If 1 wants to write virtually "what's incorrect alongside economics," such a huge separate betwixt academic query ideas too the ideas running our policy institution is non a proficient situation.
The correct agency to address this is alongside models -- written down, objective models, non pundit prognostications -- too data. What accounts, quantitatively, for our experience? I come across old-fashioned Keynesianism losing because, having dramatically failed that exam once, its advocates are unwilling to practise too thus again, preferring a drive of personal assail inward the pop press. Models facial expression information inward the pages of the AER, the JPE, the QJE, too Econometrica. If old-time Keynesianism actually does concern human relationship for the data, write it downwardly too let's see.
